TRACTION-GAS-ENGINE GEABING.

Specification of Letters Patent. Application filed February 12, 1810. Serial No. 543,624.

To all whom it may concern: I

Be it known that I, EMORY C. GRIZZELL,

tate of Kansas, have invented a new and useful Traction-Gas-Engine Gearing; and I do hereby declare the following to be afull,

clear, and exact description of the invention,

such as will enable 0t ers skilled in the art to which it appertains to make and use the same.

This invention pertains to a new and useful traction gas engine gearing adapted for use in connection with threshing machines and the like.

' The rimary object of the invention is the pro uction of a device of this desi n in which a new and novel gearing is emp oyed comprising a multiple of gears so arranged with regard to the traction wheels, the driven crank shaft (which is driven by the pistons of the oppositely arran ed engine cylinder) and the transmission riction clutch, in order that the various moving parts of the structure may easily operate and in unison, and furthermore, to allow the various parts to be easily and quickly reversed in their movements.

A further object of the invention is the provision of a transmission friction clutch, whereby a fan (not shown) for a radiator to a cooling system (not shown) may be driven through the medium of a belt connection (not shown), said transmission friction clutch being so constructed as to reverse the motion of the engine and its. gearing thereof.

n. this specification and the drawings annexed hereto, a articular design of device is adheredto, but the invention is not to be confined to this particular design.

The device, in its reduction to practice,

may require changes and variations; the

right thereto belongs to the applicant, pro

vided such changes and variations are comprehended by the appended claims.

Further objects and combinations of parts will .be hereinafter set forth and pointed out in the appended claims.

Figure 1, in the drawings, is a top plan view of a traction gas engine gearing, constructed in accordance withthe invention. Fig. 2 is a sectional view on line 2-2 of Fig. 1, displaying various parts of the invention in side elevation. Fig. 3.is a transverse sectional view on line 3-3 of Fig. 1, showing the transmission friction clutch in elevation, the mounting of the crank shaft u on the bearing beams of the frame, and s owing various other tion. Fi 4 1s a .sectional view on line 44 of P ig. 1, looking in the direction of the arrow. Fig. 5 is an enlarged detail sectional view of the transmission friction clutch. Fig. 6 is a sectional view upon line 66 of Fig. 5, looking in the direction of the arrow and showing the clutch wheel and the clutches in side elevation, there being one of the clutch members shown in section. Fig. 7 is a sectional view on line 77 of Fig. 5, showing one of the clutches in elevation, and further displaying how a portion of the clutch member is fixed to rotate with a rectangular sha ed sleeve (which is mounted on a cylin rical shaft). Fig. 8 is a sectional View on line 88 of Fig. 5, showing how the gear 24 is keyed to rotate with a cylindrical ortion of another sleeve (which is mounted upon the section 21 of the shaft 21) so the section 21 of the shaft 21 will rotate freely when the clutch members are not frictionally engaging the clutch wheel. Fi 9 is a sectional view upon line 9-9 of Fig. 5, illustrating the manner of mountin the slidable clutch hub upon a i'pctangu ar portion of the sleeve shown in Referring to the drawings, 1 designates a frame-work of the traction engine upon which a lurality of bearing beams 2 are supported which bearing beams form a bed base for the'support of the driven crank shaft and various other shafts of the multiple of gears.

3, 41, 5 and 6 designate engine cylinders in which the combustion takes place, in the usual manner, in order to operate the pistons 7, 8, 9 and 10. These pistons are provided with pitman rods 11, 12, 13 and 14, which are connected to the cranks 19 and 20 of the crank shaft 21 which is mounted in suitable bearings 22 of t e bearing beams 2).

Mounted u onthe crank shaft 21 is a transmission iction clutch wheel 23, which is ada ted to transmit power to a fan (not shown of a radiator to a cooling system (not shown). The clutches or members 23 and 23 of the clutch wheel may be thrown in and out of contact with the, wheel 23 in order to reverse the motion of the gearing, the o erations of said clutches or members will o hereinafter. more fully set forth.

Patented se t. 20, 1910.

parts of the device in eleva i 24 and sprocket Mounted upon the crank shaft 21 adjacent r the transmission friction wheel is a pinion or ear 24 (which meshes with a spur gear 25.) ounted upon the shaft 21 and also adjacent the transmission friction clutch is a sprocket wheel 26, about which a sprocket.

chain 27 travels.

The spur gear 25 is journaled upon and 5 and are mounted upon shafts 32, which shafts 32 are journaled in suitable bearings 33 of the bearlng beams, as shown clearly 1n.

%lpon the outer ends of the shafts 32 are pinions or gears 34 and 34 (which mesh with the spur gears 35 and 35.) The spur gears 35 and 35 are mounted upon the shaft 36 (which is journaled in suitable bearlngs 37 on the lower portion of the frame 1.)

38 denotes traction wheels of the usual structure which are'journaled upon and designed to rotate with the shaft 36, and when power is transmitted to the shaft 36 through the multiple of gears, the traction wheels 38 3 will rotate, thereby propelling the engine in a forward or rearward direction.

J ournaled in suitable bearings 39 upon two central bearing beams are shafts 40 and 41 (which are cared together by two pinions 42 and 43.

42 meshes with the spur gear 25. J ournaled upon and designed to rotate with the shaft 41 is a s rocket 44 (about which the sprocket chain 2 travels.)

sections 21, 21 and 21, and the sprocket wheel '26 and gear are carried by the section 21, the purpose of which structure will be hereinafter set'forth.

to which belts chine v(not shown.)

21, in order to rotate therewith. .Loosel journaled upon the section 21 of the 'sha t i 21 are sleeves-'56 and 157, the end portions 58 i of which are cylindrical, as shown clearly in Fig. 6, and to these end portions the pinion "wheel 26 are keyed, by means of the feathers '59. It will be ob served that the wheel 24 and sprocket wheel 26 will rotate with the said sleeves. The remaining portions of the sleeves 56 and 57 are rectangular in cross section as will be clearly seen at 60 in Figs. 6 and, as well as in Fig. 9. Mounted upon the rectangular portions of said sleeves are clutch hub mem- Y The said pinion or gear.

The crank shaft21 is constructed in 3' The friction c1utchwl1eel23 is keyed, as shown at 55, to the section 21 oflthe shaft here 61 and 62, from which spokes of rods 63 and 64 project at right angles to one another. The clutch members or shoes 23" and 23 are mounted upon the ends of these rods or spokes to slide outwardly, as shown clearly at 65 in Fi 6;.in'order to be thrown in contact with th clutch wheel 23. The clutch members or shoes are providedwith integral shells 66, in which springs 67, as shown in Fig. 6, are mounted. Passing through the springs are the threaded ends 68 of the rods 69, and threaded upon the rods 69 are nuts or members 70, between which and the clutch members or shoes the said springs are interposed. By adjusting these nuts toward the springs, it will be clearly seen that the tendency of the clutch members or shoes is to engage the clutch wheel. Also, mounted upon the rectangular portions of the sleeves 56 and 57 are slidable clutch hubs 71 and 72, which are provided with annular grooves 73 'for the reception of the collars 74.

Projecting from the collars 74 are pins 75, with which the forked ends of the levers 90 76 and 77 engage. These levers 76 and 77 are pivoted at 78 to the frame-work of the machine, and by oscillating the levers, the slidable clutch hubs may be moved toward or away from the clutch wheel.

Connecting the slidable clutch hubs and the clutch members or shoes are rods 79 and 80, and throughthese connecting rods, the clutch members or shoes may be thrown in engagement with the clutch wheel, when the slidable clutch hubs are moved toward the clutch wheel. When the slidable clutch hubs are moved away. from the clutch wheel,

' the clutch members or shoes are drawn 1nwardly and toward the crank shaft, against the tension of 'the springs 67. When operating the clutch members or shoes, so as to contact with the clutch wheel, they are asby the expansion of the springs 67. When it is desired to traverse the machine forward-the lever adjacent the pinion 24 is operated,so that the clutch "members or shoes .23 are thrown in engagement with (the clutch wheel. In thiscase the gear 24 is rotated in the direction of the arrow 81, which in turn rotates the spur gear 25 in the ifflppflslte direction, as indicated bythe arrow 82. By rotating the gear 25 and the shaft.

28 this directlon, the gear 30 is rotated in the :same direction, consequentl the gear 31 is revolved in the opposite 'rection, the. arrow 83 indicating its direction. The gear 34 "is rotated in t e same direction as the gear 31, therefore the gear 35 is rotate'din the op osite direction, which direction is shown the arrow 85. When the gears, the motions of which have just been set forth, are 0 erated in this manner, the sprocket whee 26 is rotated idly, as well as the clutch members or shoes 23", but the 130 gears 30, 31, 34 and 35 are rotated in the same direction as the gears 30, 31 34 and 35. To reverse the machine, the lever 17 adjacent the sprocket wheel 26 is operated, so as to draw the clutch members or shoes 23 in engagement with the clutch wheel 23, and by so doing the directions of the rotation of the pinions 42 and 43, and the spur gear 25, as well as the sprocket wheel 44, are changed, as indicated by the arrows 87, 88, 89 and 90. By changing the direction of rotation of the gear 25, it will be observed that the direction of rotation of the gears 30,

. 30, 31, 31, 34, 34, 35 and 35" are changed.

From the above, it will be observed that by throwing the clutch members 23 in engage- .ment with the clutch wheel, that the machine will be driven rearwardly. I

The sections 21, 21 and 21 are coupled together, shown more clearly in Fig. 5, by means of collars 93. Penetrating the flanges of the collars are bolts 95 to hold them securely in lace. These collars are secured to the sections of the shaft 21, by means of pins 94, in order that the sections of the shaft 21 may rotate as one body.

Having thus fully set forth the invention, what is claimed as new and useful is 1.
